It doesn't cover all the cases, but you're aware of the 'X' variant
for chmod (aka: turn on the x bit if a directory, but also if it
has already an x bit somewhere else, alas):

  tomas@trotzki:~$ ls -ald f*b
  -rw-r--r-- 1 tomas tomas    0 Aug  6 08:49 fib
  drwxr-xr-x 2 tomas tomas 4096 Aug  6 08:48 fob
  -rwxr--r-- 1 tomas tomas    0 Aug  6 08:48 fub

  tomas@trotzki:~$ chmod go+X f?b

  tomas@trotzki:~$ ls -ald f*b
  -rw-r--r-- 1 tomas tomas    0 Aug  6 08:49 fib
  drwxr-xr-x 2 tomas tomas 4096 Aug  6 08:48 fob
  -rwxr-xr-x 1 tomas tomas    0 Aug  6 08:48 fub

It might /sometimes/ do what you want (i.e. in the most common case
where you want dirs to have the x bit set, but regular files not).
