cmdutil: make commit message shown in text editor customizable by template
This patch makes commit message shown in text editor customizable by
template. For example, this can advertise:
- sample commit messages for routine works,
- points to call attention before commit,
- message of the day, and so on
To show commit message correctly even in problematic encoding, this
patch chooses the latter below:
- replace "buildcommittext" with "buildcommittemplate" completely
- invoke "buildcommittemplate" only if '[committemplate] changeset'
is configured explicitly
For example, if multibyte character ending with backslash (0x5c) is
followed by ASCII character 'n' in the customized template, sequence
of backslash and 'n' is treated as line-feed unexpectedly (and
multibyte character is broken, too).
This corruption occurs in 'decode("string-escape")' while parsing
template string.
