23 /* Read a table, line by line, from a file.
25 A table line has several forms:
30 type == table_colon_entry
32 Fields points to a NULL terminated list of pointers.
36 <tab> <text> <nl> { <tab> <text> <nl> }
37 type == table_code_entry
39 The leading tab at the start of each line is discarded.
40 fields[i] is the i'th line with the <nl> discarded.
45 "{" <ignore-text> <nl> { <text> <nl> } "}" <ignore-text> <nl>
46 type == table_code_entry
48 The leading/trailing {/} lines are discarded.
49 Lines containing two leading spaces have those spaces striped.
50 fields[i] is the i'th line with the <nl> discarded.
52 In addition, the table parser reconises and handles internally the
53 following (when not in a code block):
55 "#" <line-nr> '"' <file> '"'
57 As per CPP/CC, treat following lines as if they were taken from
58 <file> starting at <line-nr>
