Patch #275 - 2011/09/11 * add ash, zsh to known shells for resize. * modify resize to reuse the logic from xterm which determines the actual logon-user's shell if $SHELL is not set. * revert the unsetenv("SHELL") added in patch #272. * an unsetenv("SHELL") added in patch #272 to help ensure that luit would get the user's shell consistently did not work as expected for cases where multiple names are in the password-file for a given uid. That was because changes in patch #157 to handle this situation did not take into account that repeated calls to getpwnam and getpwuid return a pointer to the same static buffer. Fixed the older logic to work as intended, by ensuring that the passwd-data from each call is stored separately (report by Paul Keusemann). * adjust ifdef's for putenv and unsetenv in case only one of those is provided on a given platform. * correct comparison used in ExposeContains macro from patch #274 changes, to handle window-dragging (patch by Todd Eigenschink). -- Thomas E.
