 * matrix functions: revise ModeMatrix, mat_function, dispJordan, diag, JF
 * signum: do not declare signum real- or integer-valued
 * carg: declare carg real-valued
 * parser: add L, l, W, and w to list of exponent marker characters


   Changes in share:

 * package stringproc: new functions readchar, md5sum, base64


   Other changes:

 * documentation: minor changes to make Texinfo 5 happy
