The `==` operator is only available in `[[`, which is a bash-ism also supported by zsh. This mix-up was causing the following completion error in zsh: > __git_ls_files_helper:7: = not found (That message refers to the extraneous symbol in `==` ← `=`). This updates that comparison to use a single `=` inside the basic `[ … ]` test conditional. Although this fix is inconsistent with the other comparisons in this file, which use `[[ … == … ]]`, and the two expressions are functionally identical in this context, that approach was rejected due to a preference for `[`. Signed-off-by: Robert Estelle --- completion: Fix incorrect bash/zsh string equality check v2: This updates the comparison to remove the extraneous = symbol in ==, and use the [ … ] conditional instead. v1: (rejected) updated that comparison to use the extended [[ … ]] conditional for consistency with the other checks in this file. This fixes an error in contrib/completion/git-completion.bash caused by the incorrect use of == (vs. single =) inside a basic [/test command. Double-equals == should only be used with the extended [[ comparison.
