Bug in get_word in main.c

[Bohdan R. Rau]

 Hi all

 I just found annoying bug in get_word function.

 The ch variable is declared as signed char, and all calls to get_char, 
 where result is treated as character, are casted do signed char.
 In this case comparison like 'ch > SPACE' has no sense, because for 
 example all accented letters in Latin scripts or all letters in Cyrillic 
 will be treated as non-word.
 In effect, function get_word will find beginning of word only if first 
 word characters is 7-bit ascii.

 Dirty and fast solution:

 1) change declaration of ch variable from char to u_char
 2) replace all (char) get_char calls into (u_char) get_char.

 Works for me.

 I could provide "dirty and fast" patch, but I think the 'ch > SPACE' 
 comparison would be changed into some more realistic function - 
 something like:

 is_word_boundary(int ch1, int ch2)
 {
    return is_printable(ch1) != is_printable(ch2);
 }

 By the way - would you give me definition of "word" in speakup's scope? 
 Is it "longest string containing only printable characters"?
