keyword: specific regular expressions depending on read mode

More safeguarding against accidental (un)expansion:

Reading filelog: act only on \$(kw1|kw2|..)\$ as keywords are always
                 stored unexpanded.
Reading wdir:    act only on \$(kw1|kw2|..): [^$\n\r]*? \$ as we only
                 are interested in expanded keywords in this situation.
                 Note: we cannot use ..): [^$\n\r]+? \$ because e.g.
                 the {branch} template might be empty.

hg record is a special case as we read from the working directory and
need one regex each for modified and added files. Therefore test
recording an added file.

This way we finally also forbid sequences like $Id:  $ being treated
as keywords.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help
