From 5501f500b22116166c892d632382c9d497da822c Mon Sep 17 00:00:00 2001 From: Robert Abel Date: Wed, 6 Dec 2017 00:39:11 +0100 Subject: git-prompt: make __git_eread intended use explicit __git_eread is used to read a single line of a given file (if it exists) into a single variable stripping the EOL. This patch removes the unused capability to split file contents into tokens by passing multiple variable names. Add a comment and explicitly use $2 instead of misleading $@ as argument to the read builtin command.
