Lucha Ignore Enhancements

[djschleen]

The .luchaignore file will only ignore files and folders (this needs to be hardened as well), but needs to also ignore only a single line in a file if defined.

Examples:

test.csv:1:1
test.csv:4:1

The format of above is [filename]:[line]:[character]. Eventually [character] could be a range, but character is out of scope for this issue.

Desired functionality: If a file name is preceded by a colon and has a line number, ignore that line in processing.
