Change docs for glob parameter

[eliasre]

This might be an issue with operating system (Mac OS Sierra 10.12.6), npm (5.6.0) or any other thing, or it might be an issue for everyone, but:

When I follow the example code and submit a glob as parameter -i src//.ts, the filenames are unpacked and apparently submitted as an array to the extractor. The globstar path is not respected and I am only scanning the toplevel folder (src//*.ts). By submitting the glob-pattern within a string ('src//*.ts) this is avoided. The unwrapped parameter is working for me in the example project because averything is nested 1 level deep.

The example project and documentations should probably use a glob parameter wrapped in a string

Maybe this is a duplicate of #2

I am having a similar issue. Under windows using git bash there is no globstar. So even when I wrap it in a string it only enters the first subdirectory. To extract all translations I have to pass all directories and their subdirectories to the --input option. For every module/component which kind of sucks.

Example:

ngx-extractor \
-i src/app/*.ts \
-i src/app/auth/**/*.ts \
-i src/app/auth/*.ts \
-i src/app/core/*.ts \
-i src/app/core/**/*.ts \
-i src/app/posts-module/*.ts \
-i src/app/posts-module/**/*.ts \
-f xlf \
-o src/locale/messages.xlf \
-l en
