-Subject: [PATCH] Fix crash in lexer refill (reported by Agostino Sarubbo).
-
-The crash happened in a rare case of a very long lexeme that doen't fit
-into the buffer, forcing buffer reallocation.
-
-The crash was caused by an incorrect calculation of the shift offset
-(it was smaller than necessary). As a consequence, the data from buffer
-start and up to the beginning of the current lexeme was not discarded
-(as it should have been), resulting in less free space for new data than
-expected.
