Hi Brenton,

I do indeed have strong feelings about tabs :-)
Like remove all leading ones, and any TAB-after-space.
[rules to enforce that are in maint.mk and cfg.mk]
However, a few times when a crusade led me to do
what you're proposing and eliminate all of them, I later realized
that I found value in TAB-aligned comments, and actually regretted
performing that particular TAB->SP+ conversion.

On a code normalization front, I am inclined to fully automate the
process, and have spent time (though not recently) trying to find
the combination of settings in the uncrustify tool that recreate the
style we use in a few projects. If you feel like pursuing this, please
look at uncrustify and see if you can minimize the changes required
to move grep to something uncrustify-generated.

Bottom line, I'm not terribly keen on changing comment-aligning
tabs to spaces.

Thanks,
Jim
