There is one case where mixing tabs and spaces might be useful.
<tab> <tab> printf("%s: %d, %d",
<tab> <tab> <spc> some_string_variable,
<tab> <tab> <spc> some_integer,
<tab> <tab> <spc> some_integer2);
Tabs can make sure that no matter what the user wishes to set his tab
stops at, the indentation is always consistent. Spaces can then allow
for sub-positioning, so that the argument list always lines up no matter
what the tab stop settings. If you always replace spaces with tabs,
this can get messy. Which is probably why many folks prefer to convert
all tabs to spaces.
