GNU style says this should be indented only two spaces from the brace.

[bsy, 2012/02/15 19:33:29]

Done.  (well, i indented the brace further.)

GNU style says this whole block is indented two spaces from the if (and likewise
for the else).

[bsy, 2012/02/15 19:33:29]

Done.

GNU style avoids superfluous braces for single-line cases.

[bsy, 2012/02/15 19:33:29]

Done.
