commands: automatically word-wrap cmdline options
Some of the descriptions of command line options were getting quite
long, and when translated they are likely to grow even longer. This
word-wraps them at 70 characters, just like the help texts.
We could have opted to wrap them at the terminal width instead, but I
think it looks better to have them be consistent with the help texts.
changeset = '{rev}{tags}{parents} {node|short} {date|isodate} {author|user}\n {desc|firstline|strip}\n\n'
changeset_quiet = '{rev}:{node|short}\n'
start_tags = '['
tag = '{tag},'
last_tag = '{tag}]'
start_parents = ':'
parent = '{rev},'
last_parent = '{rev}'
