Change the command list to always include #shell and #suspend so that
a user's preferred key bindings can span platforms without worrying
about whether those exist or not. They're still effectively no-ops
when compiled out.
'#?' suppresses them from the list of displayed commands. Interface-
specific extended command handling may want to check new extcmd.flag
value CMD_NOT_AVAILABLE to do the same, but failing to do so shouldn't
pose a problem. They behave sanely if executed when not supported.
This is a modified version of Jason Dorje Short's key rebinding
patch, and allows also binding special keys, such as the ones
used in getloc and getpos.
One of the ways to play NetHack on nethack.alt.org is via a HTML
terminal in browser. Unfortunately this means several ctrl-key
combinations cannot be entered, because the browser intercepts
those. Similar thing applies to some international keyboard layouts
on Windows. With this patch, the user can just rebind the command
to a key that works best for them.
I've tested this on Linux TTY, X11, and Windows TTY and GUI.
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.
