[TxMt] Re: Reformat comment command

[Daniel Grady]

Hi, I'm not sure if anyone's brought this up before, but I think there are
three problems with the Reformat Comment command in the Source bundle:

1. It doesn't respect the wrap column (the TM_COLUMNS variable)
2. It adds an extra newline at the end of the comment
3. It doesn't correctly handle comments that are indented

Are these actually problems, or am I thinking about the purpose the command
incorrectly? If they are actually problems, I think the way to fix them is by
changing two of the lines in the command, and switching the Input to Selected
Text or Line (rather than Selected Text or Scope) since this will pass leading
whitespace to the rubywrap script. The updated command is included below.

Is this right? I came across this problem while fiddling with a Python script;
I'm not a very experienced programmer and I really have no idea if these
changes cause problems with other languages. Thanks for any feedback!
