 Most of the work is done by the inner function \fBresize_term\fR.
-The outer function \fBresizeterm\fR adds bookkeeping for the \fBSIGWINCH\fP handler.

 When resizing the windows,
 \fBresize_term\fR blank-fills the areas that are extended.
 The calling application should fill in these areas with appropriate data.
+.PP
 The \fBresize_term\fR function attempts to resize all windows.
 However, due to the calling convention of pads,
 it is not possible to resize these
 without additional interaction with the application.
+.PP
+When resizing windows, \fBresize_term\fR recursively adjusts subwindows,
+keeping them within the updated parent window's limits.
+If a top-level window happens to extend to the screen's limits,
+then on resizing the window, \fBresize_term\fR will keep the window
+extending to the corresponding limit, regardless of whether the
+screen has shrunk or grown.
 .SS is_term_resized

 A support function \fBis_term_resized\fR is provided so that applications
 can check if the \fBresize_term\fR function would modify the window structures.
