Subject: test-lib: Fix say_color () not to interpret \a\b\c in the message
X-Git-Tag: v1.8.0.1~22^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7bc0911d037f0a144d8c227f58693da0c9c77b2a;p=git

test-lib: Fix say_color () not to interpret \a\b\c in the message

When running with color disabled (e.g. under prove to produce TAP
output), say_color() helper function is defined to use echo to show
the message.  With a message that ends with "\c", echo is allowed to
interpret it as "Do not end the line with LF".

Use printf "%s\n" to emit the message literally.
