 - tuning_pye.py: A file with some improved replacements for functions of pye:
 a) find_in_file() supporting regular expressions,
 b) line_edit() supporting the cursor left/right/home/end keys, and
 c) expandtabs() and packtabs() with a second argument for tabsize (not for pye, but maybe useful)

+**Short Version History**
+
+**1.0** Initial release with all the basic functions
+**1.1** Same function set, but simplified keyboard mapping. 
+- Removed the duplicated definitions for cursor motion keys.
+- Allowed both \r and \n for ENTER, and both \x08 and \x7f for BACKSPACE, which avoid some hazzle with terminal settings. 
+- Removed auto-indent from the minimal version.
+**1.2** Mouse support added, as well as some other minor changes.
+- Simple Mouse support for scrolling and placing the cursor
+- Flags setting for search case, autoindent on/off and statusline on/off
+- GOTO line sets cursor to the middle row
+- The function pye(..) returns a value now
+**1.3** UNDO added. Added a multilevel UNDO (Ctrl-Z) for most functions that change the content. Other changes:
+- Backspace at the first non-blank character mimics BackTab, if Auto-indent is enabled
+- Added a REDRAW (Ctrl-E) function, which checks for the changed screen size after the window size has been changed.
+- Added a line number column on the left side of the screen (can be turned off).
+- Improved the scrolling speed, such that it lags less.
+- Some code simplification and straightening, such that functions group better and a easier to understand.
+**1.4** GET file added. Adding a function GET (Ctrl-O), which inserts the content of a file before the current line. Other changes:
+- Both HOME and END stop at start of text is passing by on their way to their destination.
+- Flag allowing to replace spaces by Tab when writing the file, complementary to what is done while reading. Tabsize is 8. A tab is inserted whenever possible, even if it replaced a single space character.
+- Fixed a mild amnesia in UNDO
+**1.5** WiPy Port and body shaping:
+- Support for WiPy added. WiPy runs only the minimal version.
+- Aligned function set of the minimal version, in order to comply with WiPy. Dropped Mouse support, GET file, Line number column, Delete in Line edit mode, and write tabs; but included the buffer functions Yank, Dup & ZAP, Tab and Backtab.
+- LEFT and RIGHT move to the adjacent line if needed
+- When used with Linux **and** CPython, a terminal window resize cause redrawing the screen content. The REDRAW key (Ctrl-E) stays functional and is required for all other use cases, when the window size is changed. 
+- HOME toggles again between start-of-line and start-of-text. END moves always to end-of-line
+- Dropped context sensitive behaviour of Tab, Backtab, Backspace and Delete. Too confusing. 
+- Dropped the line number column, and made the status line permanent in all modes.
+- Rearranged the code such that any platform related sections are grouped together.
