gendoc: fix synopsis

The synopsis is used as an inline literal when generating the manpage.
There should not be any whitespace on the inside of the quotation
marks in inline literals.

Commands with an empty synopsis (such as tags) produces ``tags `` as
synopsis, which triggers a warning.

# simple script to be used in hooks
# copy it to the current directory when the test starts:
#
#     cp "$TESTDIR"/printenv.py .
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python ../printenv.py <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
