bazel-complete.bash doesnt do tab completion on bash 4.4.20(1)-release

[shantanu-gontia]

Description of the bug:

The Bazel completion plugin for Bash downloaded with bazel doesn't work for me. I'm using Bash 4.4.20(1)-release
I'm not sure if this fails to run on newer versions, I haven't tested this yet.

I'm not too familiar with bash scripting, so I don't know if this is invalid syntax or perhaps some error in parsing the file with the bash version I'm on.

Which category does this issue belong to?

CLI

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

• Install bash-4.4.20(1)
• Install Bazel 6.4.20
• Create a Bazel Repo
• Try autocomplete

Which operating system are you running Bazel on?

Linux

What is the output of bazel info release?

release 6.4.0

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

After some fiddling, what worked for me was removing the comments after every condition in the case...easc blocks

For instance, removing the comments of the form

bazel/scripts/bazel-complete-template.bash

Line 756 in bb79b3c

*) # Expand target pattern

i.e. comments following one of the case matches in the same line.
