描述

For example:

$ rg -e foo -f src/search_stream.rs 
Error parsing regex near 'fer.|*/|z{' at character offset 213: Invalid application of repetition operator to: '(?u:f)(?u:o)(?u:o)|(?u:/)*(?u:!)|(?u:T)(?u:h)(?u:e)

Aside from the badly formatted regex error message (see #395), the error message should show the file path and probably also the line number at which the error occurred.
