Trim leading space in file picker search

[aral]

Leading space in the file picker search can be trimmed to improve the experience.

e.g., your project structure:

some-file.js

Search box:

 some

Will not match some-file.js due to the leading space (which could have been accidentally entered). Since leading spaces are not allowed in file names, they can be trimmed to provide a better experience in this edge case.

Priority: low.

In what context are file names with leading spaces not allowed? On most Unix-like systems a filename may contain any bytes apart from '/' and 0.

Edit: Even with such filenames it could be useful to trim input, as it is indeed a very uncommon thing to have and those files will still be found

The search is fuzzy though: test could mean I'm trying to match my test.txt.

Hmm yeah you may want to search for a space follow by a suffix. There is related discussion in #2290 of handling spaces in the picker.
