Commit message: escapes() revamp

     Partial rewrite of escapes(), mostly changing its if-then-else
logic so that end-of-string can be checked once instead for each case.
The previous version had a bug if the input string ended with backslash
and one decimal digit (due to being lumped together with the handling
for trailing \X or \O).
CVE: CVE-2020-5253
CWE: CWE-269
Vulnerability description: NetHack before version 3.6.0 allowed malicious use of escaping of characters in the configuration file (usually .nethackrc) which could be exploited. This bug is patched in NetHack 3.6.0.
