tkdiff Code

V5.4
* Optional support for MULTIPLE Preference files w/command-line specification added
permits user configuration for disjoint projects w/conflicted SCM requirements
* Added Inline-diff suppression categories to parallel equivalent Diff options, yet
where said visualization choices are INDEPENDANT of those same Diff MATCH suppressions
* Reengineered SyncScroll preference to no longer permit fractured alignment - EVER,
except for specific features TEMPORARILY overriding it per that features needs
* New preference describes filenames to exclude from searches looking for candidate files
* Text searching now (optionally) scrolls EITHER/BOTH windows independent of the current
overall synchronized window preference setting. Allows visual alignment between the
displayed file content based on individual text searches per each window.

V5.3.1
* Within Vpath SCM context, CWD location effectively TOP-prunes stated VPATH
* Subdirs within Vpath nodes now recognized as legitimate CWD-scoped locations
* Repaired how Vpath searches for Topmost and/or Prior version
* MouseWheel now works positioned over choices WITHIN Filelist Dialog

V5.3
* Added VPATH handling, integrated to appear as yet another SCM system.

Mangled V5.2 edit repaired to re-enable directory scanning + minor comment clarifications

Repair Perforce SCM access plus miscellaneous typos

Ensure "Class" of secondary window(s) REMAIN as "Tkdiff"; not "Toplevel"

Added mouse-wheel scroll support to filelist dialog display

fixes for Tkt#78 - proper quoting to protect special chars in filenames

Duh - repair prior commit to be ONLY that change

eliminate delayed action when updating multifile display location
