Modify read and print of combining characters
Since combining characters, such as accents, modify the appearance of the
previous letter, it looks awkward in its character literal form (#\name)
since it modified the backslash. This instead prints the combining
character on a small circle.
* libguile/chars.h (SCM_CODEPOINT_DOTTED_CIRCLE): new #define
* libguile/print.c (iprint1): print combining characters on dotted circles
* libguile/read.c (scm_read_character): parse the combination of combining
characters and dotted circles
