I've kept all the existing "pretty" output and results summary as is, it just
gets a hash in front of it when TAP is enabled.

so this:

-----------------------
running ./hugepage-mmap
-----------------------
Returned address is 0xffff89e00000
First hex is 0
First hex is 3020100
[PASS]
SUMMARY: PASS=1 SKIP=0 FAIL=0

becomes this:

TAP version 13
# -----------------------
# running ./hugepage-mmap
# -----------------------
# Returned address is 0xffff89e00000
# First hex is 0
# First hex is 3020100
# [PASS]
ok 1 hugepage-mmap
# SUMMARY: PASS=1 SKIP=0 FAIL=0
1..1

If you think the latter is ofensive, then I can do the wrapping as you suggest.
