[hackers] [dmenu][PATCH] Fix C warning about using '*' in boolean context

[samee . zahur]

From: Samee Zahur <samee.za...@gmail.com>

Was getting the following warning:

  dmenu.c: In function ‘setup’:
  dmenu.c:24:30: warning: ‘*’ in boolean context, suggest ‘&&’ instead
    [-Wint-in-bool-context]
  [...]
  dmenu.c:637:9: note: in expansion of macro ‘INTERSECT’

Warning no longer emitted after fix.

Tested on gcc --version:
gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008
