Bug 19939 – std.format %13,3.2f does not count width correctly

Example code: ------- import std.stdio; void main() { writefln("^%13,3.2f$", 1.00); writefln("^%13,3.2f$", 10.00); writefln("^%13,3.2f$", 100.00); writefln("^%13,3.2f$", 1_000.00); writefln("^%13,3.2f$", 10_000.00); writefln("^%13,3.2f$", 100_000.00); writefln("^%13,3.2f$", 1_000_000.00); writefln("^%13,3.2f$", 10_000_000.00); } ------- Expected output: ------- ^ 1.00$ ^ 10.00$ ^ 100.00$ ^ 1,000.00$ ^ 10,000.00$ ^ 100,000.00$ ^ 1,000,000.00$ ^10,000,000.00$ ------- Actual output: ------- ^ 1.00$ ^ 10.00$ ^ 100.00$ ^ 1,000.00$ ^ 10,000.00$ ^ 100,000.00$ ^ 1,000,000.00$ ^10,000,000.00$ ------- It seems that there is an off-by-1 error in the reckoning for width when formatting floating-point values with a format that contains a `,n` flag.
