* misc/mntent_r.c (__hasmntopt): Check p[optlen] even when p == rest.
Start searching for next comma at p rather than rest.
* misc/Makefile (tests): Add tst-mntent2.
* misc/tst-mntent2.c: New test.
* misc/getusershell.c (initshells): Check for integer overflows.
Make strings buffer one bigger as fgets always succeeds when second
argument is 1. Don't use calloc for shells array. Disallow
/ as shell.
