Message-ID: <2b74889c2a323f03be477ffdf9ff388405779c3b.1617627856.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.924.git.1617627856.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The use of 'grep' inside test_subcommand uses general patterns, leading to sometimes needing escape characters to avoid incorrect matches. Further, some platforms interpret different glob characters differently.

Use 'grep -F' to use an exact match. This requires removing escape characters from existing callers. Luckily, this is only one test that expects refspecs as part of the subcommand.
