| * | | | Tweak the Tcl_UtfPrev() implementation for TCL_UTF_MAX=4. This fixes 10 ↵jan.nijtmans2020-05-111-34/+28
| | | | | | | | | | | | | | | | | | | | testcases in 4 groups (utf-7.10, utf-7.15, utf-7.40 and utf-7.48) , where Tcl_UtfPrev() didn't jump to the beginning of the UTF-8 character, even though there was no limitation which prevented that. So, this is actually a bug-fix for the TIP #389 implementation.

| | | | | | | | | | | | | | | For start bytes F0-F4, case TCL_UTF_MAX=4, Tcl_UtfToUniChar() reads 3 bytes but only advances 1 byte. So Tcl_UtfCharComplete() must make sure 3 bytes are available, not 1. Adapt Tcl_UtfCharComplete() accordingly. No change for TCL_UTF_MAX=[3|6]

| | | | | | | | | | | | | | | | | | | | | | | | Make sure that Tcl_UtfPrev() never reads more than 3 trail bytes (or 4 when TCL_UTF_MAX > 4). Those are the same limits as for Tcl_UtfNext() and Tcl_UtfToUniChar()
