#240 gatekeeper crash when -b/-e out of order

[Brian Walenz]

gatekeeper -b 48717 -e 48171 -dumpfasta frg48717 test.gkpStore

(note dyslexia on -e range)

Backtrace (demangled):

Fixed in r4596. And again in r4597.

Now reports:

ERROR: incorrect range: -b (48717) must be no larger than -e (48171).
