Jean-François Burnol submitted an update to the
mathastext
package.
Summary description: Use the text font in math mode License type: lppl
Announcement text: ----------------------------------------------------------------------
* A new command sets up the amount of space to be automatically inserted before the derivative glyph (useful when using an upright font).
* The scope of the math alphabets has been extended to apply to the non-alphabetical characters, and also to operator names. In usual math mode $mathbf{(sin(n!)<cos(x)?)}$ changes only the font for n and x. With mathastext and if not told otherwise, /everything/ in the formula above will respond to mathbf (and the automatic spaces are left untouched).
* The documentation has been improved. The package file is self-extracting from the dtx, and four additional test files are also produced during `latex mathastext.dtx'.
