Subject: Move another common functionality (reproduced so far with cut'n'paste)
X-Git-Tag: BEN_FIPS_TEST_4^2~11^2~1
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=03ddbdd9b99ea60d0967b831ffc1fe93ae7f9792;p=openssl

Move another common functionality (reproduced so far with cut'n'paste)
to apps.c, and give it the hopefully descriptive name parse_yesno().
