I did my best to exempt some of the bigger aligned blocks from the reformatting
using the /* clang-format off */ and /* clang-format on */ tags. Probably some
that shouldn't have been formatted were anyway; if you encounter them, please
fix.
The clang-format tags were left in on the basis that it's much easier to prune
those out later than to put them back in, and it means that, modulo my custom
version of clang-format, I should be able to run clang-format on the source tree
again without changing anything, now that Pat has fixed the VA_DECL issues.
Move the code for determining monster class from user's input string
out of do_class_genocide() and into new routine name_to_monclass(). I'm
planning to use it when name_to_mon fails to match anything for controlled
polymorph (not ready for prime time yet).
Also, avoid getting stuck in a loop if hangup occurs while prompting
player for class of monster to genocide. ESC, whether deliberate or fake
input after hangup, will now be the same as specifying "none", throwing
away the genocide opportunity.
