doc: unify help text for "--edit" option
This patch changes help text for "--edit" option of commands below:
- fetch
- qnew
- qrefresh
- qfold
- commit
- tag
This unification reduces translation cost, too.
This patch chooses not "further edit commit message already specified"
(of "hg commit") but "invoke editor on commit messages" as unified
help text for "--edit" option, because the latter is much older than
the former.
