This makes it possible to remove just comment lines from log messages during a histedit operation, leaving the rest of the log message as-is. The behaviour of treating changes to comment lines as no-ops was coded to prevent mistakes during 'got commit/import/tag', where the command will error out if the log message template is not modified. This is not appropriate for histedit because histedit is used to fix such mistakes. ok millert@

got_error_fmt() could eventually replace got_error_path() which has already been used to construct errors with strings that are not actually paths... ok millert@

Otherwise, ncurses will replace them with some printable representation whose width we can't predict, and wunctrl() fails to return the replacement for 0x80..0x9f. ok stsp

If the histedit log message editor exits without saving its buffer, Got threw away log messages of all commits which were folded. Only the last commit message is preserved, which could be something meaningless like "fixup". Instead, preserve the initial editor buffer content as-is. That is not going to be an ideal log message, but doesn't throw away information and stands out visually because the newly created log message will start with a comment like '# log message of folded commit a0ff...'
