+/* Read a table, line by line, from a file.
+
+ A table line has several forms:
+
+ Field line:
+
+ <text> { ":" <text> }
+ type == table_colon_entry
+
+ Fields points to a NULL terminated list of pointers.
+
+ Tab indented block:
+
+ <tab> <text> <nl> { <tab> <text> <nl> }
+ type == table_code_entry
+
+ The leading tab at the start of each line is discarded.
+ fields[i] is the i'th line with the <nl> discarded.
+
+
+ Code block:
+
+ "{" <ignore-text> <nl> { <text> <nl> } "}" <ignore-text> <nl>
+ type == table_code_entry
+
+ The leading/trailing {/} lines are discarded.
+ Lines containing two leading spaces have those spaces striped.
+ fields[i] is the i'th line with the <nl> discarded.
+
+ In addition, the table parser reconises and handles internally the
+ following (when not in a code block):
+
+ "#" <line-nr> '"' <file> '"'
+
+ As per CPP/CC, treat following lines as if they were taken from
+ <file> starting at <line-nr>
+
+ No support for CPP's "#if/#else/#endif" style conditions are
+ planned. */
