** buttons to make sure the states are saved even after a cancel operation.
**
** If sticky case sensitivity is requested, the behaviour is as follows:
** The first time "Regular expression" is checked, "Match case" gets
** checked too. Thereafter, checking or unchecking "Regular expression"
** restores the "Match case" button to the setting it had the last
** time when literals or REs where used.
** Without sticky behaviour, the state of the Regex button doesn't influence
** the state of the Case Sensitive button.
**
** Independently, the state of the buttons is always restored to the
** default state when a dialog is popped up, and when the user returns
** from stepping through the search history.
**
** NOTE: similar call-backs exist for the incremental search bar; see window.c.
