in the same way as groff:
* \\ is always reduced to \
* \. is always reduced to .
* other undefined escape sequences are usually reduced to the escape name,
for example \G to G, except during the expansion of expanding escape
sequences having the standard argument form (in particular \* and \n),
in which case the backslash is preserved literally.
Yes, this is confusing indeed.
For example, the following have the same meaning:
* .ds \. and .ds . which is not the same as .ds \\.
* \*[\.] and \*[.] which is not the same as \*[\\.]
* .ds \G and .ds G which is not the same as .ds \\G
* \*[\G] and \*[\\G] which is not the same as \*[G] <- sic!
To feel less dirty, have a leaning toothpick, if you are so inclined.
This patch also slightly improves the string shown by the "escaped
character not allowed in a name" error message.

sshd_config; previously if the same name was reused then the last
would win (which is the opposite to how the config is supposed to
work).
While there, make the ssh_config parsing more like sshd_config.

While SIGINT (already handled) makes sense for interactive use, handling
SIGTERM in the same manner is less surprising for scripting. This lets
you do:
btrace ... & some workload; kill $!
and get the expected output.

wrong parsing class ESCAPE_SPECIAL to the better-suited parsing class
ESCAPE_UNDEF, exactly like it is already done for the similar \\,
which isn't a character escape sequence either.
No formatting change is intended just yet, but this will matter for
upcoming improvements in the parser for roff(7) macro, string, and
register names.
See the node "5.23.2 Copy Mode" in "info groff" regarding
what \\ and \. really mean.

To that end, add another argument to roff_escape()
returning the index of the escape name.
This also makes the code in roff_escape() a bit more uniform
in so far as it no longer needs the "char esc_name" local variable
but now does everything with indices into buf[].
No functional change.

be triggered by macro arguments ending in double backslashes, for
example if people wrote .Sq "\\" instead of the correct .Sq "\e".
The bug was hard to find because it caused a segfault only very rarely,
according to my measurements with a probability of less than one permille.
I'm sorry that the first one to hit the bug was an arm64 release build
run by deraadt@. Thanks to bluhm@ for providing access to an arm64
machine for debugging purposes. In the end, the bug turned out to be
architecture-independent.
The reason for the bug was that i assumed an invariant that does not exist.
The function roff_parse_comment() is very careful to make sure that the
input buffer does not end in an escape character before passing it on,
so i assumed this is still true when reaching roff_expand() immediately
afterwards. But roff_expand() can also be reached from roff_getarg(),
in which case there *can* be a lone escape character at the end of the
buffer in case copy mode processing found and converted a double
backslash.
Fix this by handling a trailing escape character correctly in the
function roff_escape().
The lesson here probably is to refrain from assuming an invariant
unless verifying that the invariant actually holds is reasonably
simple. In some cases, in particular for invariants that are important
but not simple, it might also make sense to assert(3) rather than just
assume the invariant. An assertion failure is so much better than a
buffer overrun...

There are no other return options, so adjust function signature to
void. This also allows for cleaning up its usage in vmm(4) in the
vm pmap initialization logic.

When the user requests a lock range that ends at LLONG_MAX, replace
the end point with the special EOF value -1. This avoids ambiguity
with lf_end in lf_split(). The ambiguity could result in a broken
data structure.
This change is visible to userspace in a corner case. When a lock range
has been requested with an end point at absolute position LLONG_MAX,
fcntl(F_GETLK) returns l_len == 0, instead of a positive value, for that
range. This seems consistent with FreeBSD and Linux.
