Subject: strace.1.in: rewrite conditional parts
X-Git-Tag: v5.3~96
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=91c6c7acc56499a546569d7dac9dc628633f510d;p=strace

strace.1.in: rewrite conditional parts

The current implementation doesn't work as intended since in case the
condition is false, .ig has no effect and it results in "warning: macro
'end_unwind_opt' not defined".  Rewrite it into something more dumb and
verbose, but hopefully correct.

* strace.1.in (.SH SYNOPSYS, .SS Output format): Prepend each
conditional line with respective ".if" instead of trying to wrap
it in ".ig".
