Subject: more tr portability test script fixes
X-Git-Tag: v1.5.5-rc0~5^2~11
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e85fe4d85bc7654af20ccf8054ab6922665405e5;p=git.git

more tr portability test script fixes

Dealing with NULs is not always safe with tr. On Solaris,
incoming NULs are silently deleted by both the System V and
UCB versions of tr. When converting to NULs, the System V
version works fine, but the UCB version silently ignores the
request to convert the character.

This patch changes all instances of tr using NULs to use
"perl -pe 'y///'" instead.
