The above hunk (and a few more like it) worries me: it replaces TABs
with spaces.  Is that a requirement of the GDB sources?  That would
mean we are working against the default GNU indentation style, which
I'd really hate to do.  I understand that the indent program is not
the reason for these changes.  If so, then why do we need them?
