The example code is a reduced version of my function from workers/47519,
with one bug fixed. (In workers/47519, if $1 doesn't contain spaces -
which is the case under hg mq - then $H and $s will be set to the same
value.)
Tweaked: Extended the contrib.yo hunk with details about mq.
Changes typeset such that ${newparam-notset} yields "notset" and
"typeset -p newparam" does not show an assignment to the parameter. This
is similar to the default behavior of bash and ksh, with minor differences
in typeset output.
Also add tests for some POSIX incompatibilities plus minor changes for test
harness robustness.
In the man page output, the text was underlined from the var()
to the end of the paragraph.
The texi output in affected. For instance, the text `name' in TeX
is now slanted Roman (\slshape\rmfamily) rather than slanted teletype
(\slshape\ttfamily).
The difference was mostly harmless in the common case "(see manref(foo)(42))",
which expanded to "(see man page foo(42))" under ztexi.yo, but in other
contexts the ztexi.yo expansion was was nonsensical; for example:
"the BSD manref(echo)(1) command"
"the string returned by the manref(getlogin)(3) system call"
"advisory file locking (via the manref(fcntl)(2) system call)"
"this is the exact opposite from manref(ls)(1),"
While there, copyedit some uses of manref()().
This is useful when multiple plugins add region_highlight entries and
subsequently want to remove only their own entries. Without this
functionality, recognizing one's region_highlight entries is not trivial
because the 'start' and 'end' offsets are modified by editing of $BUFFER
and the highlight specification may not be unique or distinctive.
The tweaks are as follows:
- Change zfree() to zsfree() per workers/46070.
- Remove the mem.c hunk, as it changed the signature of only one out of
two alternative definitions of zsfree(). (The definition that hunk
touched is the one that's not used by default.)
"Topics" is an experimental concept in Mercurial that augments the
current branching concept (called "named branches").

This manifested as a trailing non-underlined ".RE" in the rendered man page.
(I guess that was a man page directive, but I'm not sure how the extraneous
closing parenthesis caused it to be rendered in the output.)
