2016-09-25	sam: change license header	Marc André Tanner	1	-2/+3
	We use an adapted variant of sam's structural regular expression based command language. The initial implementation was partially based upon the following functions from sam / acme: * parse.h / edit.h (struct definitions) * cmd.c / edit.c (functions parsecmd, simpleaddr, compoundaddr) * xec.c / ecmd.c (cmdexec) * address.c / addr.c (address) It turns out the relevant code can be traced back to the initial X11 port of sam which is distributed under an ISC-like license instead of the Lucent Public License Version 1.02 used for Plan 9, plan9port and 9base. http://www.netlib.org/research/ http://www.netlib.org/research/sam.shar Hence we switch to the simpler license variant. Close #238

	For those not familiar with sam(1) more information can be found at http://sam.cat-v.org/ For now sam commands can be entered from the vis prompt via :sam <cmd> A command behaves differently depending on the mode in which it is issued: - in visual mode it behaves as if an implicit extract x command matching the current selection(s) would be preceding it. That is the command is executed once for each selection. - in normal mode: * if an address for the command was provided it is evaluated starting from the current cursor position(s) i.e. dot is set to the current cursor position. * if no address was supplied to the command then: + if multiple cursors exist, the command is executed once for every cursor with dot set to the current line of the cursor + otherwise if there is only 1 cursor then the command is executed with dot set to the whole file The command syntax was slightly tweaked to accpet more terse commands. - When specifiying text or regular expressions the trailing delimiter can be elided if the meaning is unambigious. - If only an address is provided the print command will be executed. - The print command creates a selection matching its range. - In text entry \t inserts a literal tab character (sam only recognizes \n). Hence the sam command ,x/pattern/ can be abbreviated to x/pattern If a command is successful vis switches to normal mode (and hence removes any selections), otherwise the editor is kept in visual mode. The print command "fails" by definition.
