[BZ#671607] Support command line text filters
Submitted by Adam Russell
Link to original bug (#671607)
Description
I often times find myself wishing meld supported more command line options similar to diff, especially regarding ignoring whitespace. It is inconvenient to have to start meld, manually check/uncheck the text filters I want in the preferences, and then restart meld with the actual diff I desire. Instead, I'd rather just be able to pass in options to meld in a similar fashion to diff, e.g.:
-i, --ignore-case ignore case differences in file contents -E, --ignore-tab-expansion ignore changes due to tab expansion -b, --ignore-space-change ignore changes in the amount of white space -w, --ignore-all-space ignore all white space -B, --ignore-blank-lines ignore changes whose lines are all blank -I, --ignore-matching-lines=RE ignore changes whose lines all match RE
