UltraRogue: don't swap signal handlers.
In md_shellescape(), signal handlers for SIGINT and SIGQUIT were saved
and restored, but exchanged in the process. This was fixed in the
other games by commit 600873555ec0.
Deleting md_shellescape() might have been a better fix. It is
apparently unused.

| 807 Cursor/Keypad Support | |
| 808 | |
| 809 Sadly Cursor/Keypad support is less straightforward than it should be. | |
| 810 | |
| 811 The various terminal emulators/consoles choose to differentiate the | |
| 812 cursor and keypad keys (with modifiers) in different ways (if at all!). | |
| 813 Furthermore they use different code set sequences for each key only | |
| 814 a subset of which the various curses libraries recognize. Partly due | |
| 815 to incomplete termcap/terminfo entries and partly due to inherent | |
| 816 limitations of those terminal capability databases. | |
| 817 | |
| 818 I give curses first crack at decoding the sequences. If it fails to decode | |
| 819 it we check for common ESC-prefixed sequences. | |
| 820 | |
| 821 All cursor/keypad results are translated into standard rogue movement | |
| 822 commands. | |
| 823 | |
| 824 Unmodified keys are translated to walk commands: hjklyubn | |
| 825 Modified (shift,control,alt) are translated to run commands: HJKLYUBN | |
