Turn off following symlinks

Hi,
Is it possible to turn off following symlinks in gomplate.config?

I have all files excluded except for !*.tmpl, and it still tries to follow symlinks (even though their names don't end with .tmpl).
Because files that symlinks should follow don't exist on my computer, gomplate ends with an error "failed to gather templates for rendering: walkDir: ignore matching failed for ../..: applyPatterns: stat: stat testSymlink: no such file or directory".

I can't seem to find an option to turn off following symlinks in gomplate.

If there would be a config option to change os.Stat() to os.Lstat(), it would be great.
It would read the information off of symlink, and then for my usage it would just be excluded.

@kmkacpermajor thanks for filing this - can you provide some more concrete details? what exactly does your configuration and/or gomplate commandline look like?

Sure,
To recreate this:

• touch test_file
• ln -s test_file test_link
• rm test_file
• create gomplate.config (below)
• gomplate --config gomplate.config

Error: failed to gather templates for rendering: walkDir: ignore matching failed for.: applyPatterns: stat: stat test_link: no such file or directory.

gomplate.config

excludes:
  - '*'
  - '!*.tmpl'

inputDir: .

outputMap:  |
  {{ .in | strings.ReplaceAll ".tmpl" "" }}

I'm on Ubuntu 22.04.1 LTS on WSL2, gomplate v4.1.0
