Subject: remove unnecessary null-check on parsesymbols()
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d23f26077bff24b3dc2bb9c2bea4b5bb36b02a11;p=nethack

remove unnecessary null-check on parsesymbols()

`strval` here is always non-null,
because the null-check is done in earlier code.
