Subject: t1006: extract helper functions into new 'lib-cat-file.sh'
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=fb60c49d18d1d52b6b81680586754168bc3ebc2c;p=thirdparty%2Fgit.git

t1006: extract helper functions into new 'lib-cat-file.sh'

Extract utility functions from the cat-file's test script
't1006-cat-file.sh' into a new 'lib-cat-file.sh' dedicated library file.

A subsequent commit will need these functions. This improves the code
reuse and readability, enabling future cat-file tests to share these
helpers without duplicating code.

While at it update the style of this line to follow coding
guidelines:

. "$TEST_DIRECTORY/lib-loose.sh"

to

. "$TEST_DIRECTORY"/lib-loose.sh
