on macOS, making git-gui unusable]

Thanks for working on this. I've been looking forward to the
improvement; the old behavior of not stripping comment lines has been
a long-time annoyance.
Unfortunately, however, the changes break git-gui badly on macOS. See below...

The old Tcl 8.5.9 on macOS does not have a string `cat` method, so
`string cat` crashes:
can't set "commit_type": unknown or ambiguous subcommand "cat":
must be bytelength, compare, equal, first, index, is, last,
length, map, match, range, repeat, replace, reverse, tolower,
totitle, toupper, trim, trimleft, trimright, wordend, or

The old Tcl on macOS does not support closing one end of a
bidirectional pipe, so `close $fd w` errors out:
wrong # args: should be "close channelId"
wrong # args: should be "close channelId"
while executing
"close $fd w"
I'll send a patch which resolves both problems.
