Remove mechanism for catching proc_pidinfo and statfs timeouts. It was causing crashes, but I don't understand why. Perhaps mixing ARC and non-ARC code has some problem? I saw lots of crashes on 3.1.4 where proc_pidinfo exceeded the timeout and when it finally returned there was heap corruption. It looked as though the dispatch group had been freed even though there was an outstanding reference to it. At any rate, if proc_pidinfo is hanging you're going to have a bad time even without this workaround.

Avoid looking up a negative index when you have a tail find going (i.e., the find panel is open) and you clear the buffer and it becomes empty (i.e., there's nothing before the cursor such as a prompt at the time you do cmd-k). Issue 6271

Remove incorrect tooltip on "show mark" button in prefs.

Having merged in the PR for selecting an account after opening the password manager from a trigger, add manual retain-release code and rename ivar.

Fix a bug where double-tap shift to open a hotkey window didn't work. It was using the mask for capslock instead. Issue 6251

Migrate persistent stores automatically. Should fix a bug that caused shell history to get deleted due to the addition of an index and a changed versionHashModifier

Require a minimum delay between taps of a modifier key for people whose keyboards don't debounce. Issue 6206

Don't draw any lines above the visible range. Their descenders can hang down into the display when vertical spacing is less than 100%. Issue 6223

When there is no terminal window, allow keybindings with the action "select menu item", "new window", "new tab", and "undo" to be executed. Issue 6232

Allow ~ in HTTP URL paths

Fix a crash on launch bug where a selection could have a negative endpoint, causing us to look up a long-gone line. Presumably this occurs because of the 10k line cap on session restoration.

Fix a bug where selection length was not calculated correctly. This affected various optimizations that disable features for long selections. If the column window was not set then a length of up to the grid width (but not greater) was returned.

Allow services that receive text input if up to 10k lines are selected. There has to be a limit because services grab the contents before you know they're needed, at the time the context menu opens. Issue 6218

A single click on the key icon (shown when at a password prompt on localhost) opens the password manager

Rename lastDirectoryIsRemote to lastDirectoryisUnsuitableForOldPWD and add some comments. I always find this code hard to analyze.

Initial text automatically gets a newline sent, so remove the one that used to be added when executing a script.

Issue 6067

Add an advanced pref to use the "correct" algorithm for computing line height, which involves magic incantations. It produces better results for Input Mono Condensed and seems to match what Terminal does. Issue 6159.

Also removed some unneeded baseline offset plumbing.
