cmd.exe has a command line length limit of 8192 characters. Abort if prefs.js contains strings that would get dropped while recreating the new prefs.js.
* replace /V with global VERIFY ON
* change working dir to script dir
The working dir doesn't necessarily match the script's path, depending on how the script is called. All relative paths and conditional statements using EXIST will fail whenever the working dir is not the script's own location. This fixes that.
* minimal stuff, mostly cosmetic
* prompt to run prefsCleaner under very specific circumstances
* improve -updatebatch option
* add version variable + display new script version on update
I think there's no way to get rid of ^M but hopefully with `*.bat -text` in `.gitattributes` it shouldn't be a problem because git won't do any line conversion on check-in/out.
This way the raw link as well as the file within the zip download should be in proper MSDOS CRLF format, and git status shouldn't report the file as modified either. ***fingerscrossed!!***
- Search string made case-sensitive, because Firefox preferences are.
- The script now uses regex, which allows it to understand user.js files formatted using single quotes, spaces, or tabs.
Trade-off: it can no longer reset preferences that include some special characters in their names. Not an issue for now, just something to remember.
