+ * stpaster intends to pass st(1) terminal content to dmenu(1) for rapid
+ * selection and finaly in xclip(1) for pasting easily.
+ *
+ * Remove empty lines from stdin and output full‐lines, WORDS splited by
+ * space/tab, words splited by work breakers.
+ *
+ * see st & externalpipe patch.

+ * http://st.suckless.org/patches/externalpipe
+ *
+ * is_word_break() comes from :
+ * http://st.suckless.org/patches/configwordbreak
+ *
+ * Add to config.h shortcuts :
+ * { MODKEY, 'u', externalpipe, { .s = "stpaster | sort | uniq | dmenu | removenl | xclip -in -selection primary" } },
+ *
+ * memo :
+ * 0x09 - horizontal tab
+ * 0x0a - linefeed
+ * 0x0b - vertical tab
+ * 0x0c - form feed
+ * 0x0d - carriage return
+ * 0x20 - space
